A 16-year-old client with a history of chronic ear infections when younger comes to the clinic for a health exam. No ear pain, vertigo, or hearing loss is reported during history taking. Inspection of the tympanic membranes (TM) reveals the presence of dense white patches on the TMs in both ears. Both TMs are a translucent gray with a light reflex at 5:00. All landmarks are visible. Based on these findings, which action should the nurse take next?
